Answer:
- a) 47.5 million
- b) 65.2 million
- c) 72 million
Step-by-step explanation:
It is convenient to let a spreadsheet or graphing calculator do the repetitive evaluation of a function like this. That simplifies the work and reduces errors.
The function is shown in the attachment written in Horner form, which is convenient for evaluation by hand or using a calculator.
First you divide them all by 7 to see which are greater than 19
28/7=4
84/7=12
35/7=5
105/7=15
even if you add 1 to them they all are still less than 19
so select them all
hope this helps! :)
Distribution Property.
Step-by-step explanation:
8(x+4)
8x+32
I believe the correct answer is 7 out of 24(7/24).
Length of bridge = 53 meters
Length changes expected due to changes in temperature = expansion or contraction by 21 millimeters (or 0.021 meters)
Let length of bridge at any given time be 'a'
As an absolute value equation, the situation can be expressed as:
⇒ |a-53| < 0.021
Solving the equation
⇒ -0.021 < a-53 < 0.021
⇒ 53 - 0.021 < a < 53 + 0.021
⇒ 52.979 < a < 53.021
Hence, the minimum length of the bridge can be 52.979 meters and the maximum length of the bridge can be 53.021 meters.
